Guides on getting your data out of WhatsApp, Telegram, LinkedIn, Instagram and TikTok: members, contacts, messages, comments, media and the emails creators publish, as a file you can open in Excel. Each guide compares the native way, the free workaround and the Mastros extension, and says what each one cannot do.
